CREAM Application filed May 27,

The invention generally relates to dairy equipment and primarily has for its object to provide a novel container for receiving cream and which when immersed in a cooling liql'i uid, such as cold water, will greatly facilitate the cooling of the cream contained therein.

In ordinary practices, the cream, as soon as it is separated, is poured into containers and stirred until cool. This process is slow 1 and consumes considerable time and labor, and if the task is in any measure neglected, the cream cools so slowly that it either becomes sour or does not reach the creamery in proper condition to make a high quality of butter.

Therefore, in its more detailed nature, the invention seeks to provide a novel container for receiving cream and which is provided with internal cooling liquid circulating 20 means whereby when the container is immersed in a cooling liquid a thermo-siphonic circulation of said liquid will result which will bring about a quick transfer of heat from the cream.

Other objects will in part be obvious and in part be pointed out hereinafter.

To the attainment of the aforesaid objects and ends. the invention further resides in the novel details of construction, combination and arrangement of parts, all of which will be first fully described in the following detailed description, then be particularly pointed out in the appended claims, reference being bad to the accompanying drawings, in which Figure 1 is a central longitudinal section illustrating the invention, and

Figure 2 is a horizontal section taken ,3 through the axes of the lateral ducts.

In the practical development of the invention, I provide a cylindrical container 1 con structed of any suitable material, preferably some rustless metal, and having a closed bottom 2 and an open filler top which is equipped with a removable cover 3. The container 1 is shown in cylindrical form as that is the form naturally assumed to be most desirable. "bviously, however, the M container may be formed in various other shapes if found desirable.

the space confined by the flange and the space surrounding said flange. The purpose of providing the space and the communicating apertures will become apparent as the description progresses' A hollow cooling column 7 is arranged aX-- ially within the container 1. The column 7 is open at its lower end as at 8 for commu nicationwith the space'beneath the bottom 2, while its top terminates short of the top of the container and is closed as at 9 against communication with the interior of said container. With the column 7 thus mounted, an annular cream receiving chamber- 10 is provided which surrounds the column and is subjected to the cooling influence of the cooling liquid which circulates through the columnjin a manner soon to be described.

Lateral ducts 11 provide communication between the interior of the column 7 and the exterior of the container adjacent the upper end of the container,-and these ducts also serve as means to rigidly support the upper end of the column against lateralstrains.

In practice the'containers are filled with cream and then placed in a cooling receptacle 12 containing an amount of cooling liquid'13 suitable for immersing the containers to a level above the lateral ducts 11 as indicated at 14: in Figure 1 of the drawings. 7 y

The relatively cool liquid 18 will flow through the apertures 6 into the space beneath the bottom 2, and as it becomes warmed by indirect contact with the cream will pass From the foregoing description, taken in 7 connection with' the accompanying drawings, it is thought that the novel details of construction, the manner of use and the advantages of my invention will be readily apparent to those skilled in the art to which it relates.

I claim l. A cream cooling container comprising a cylindrical shell body terminating at its lower end in an annular supporting flange and at its upper end in an open filler throat, a removable cover for the upper end of the body, a bottom having a downwardly turned annular flange contacting throughout its length with and reinforcing the supporting flange of the body, said flanges being apertured to permit cooling fluid ingress, said bottom being centrally apertured, and a fluid circulating hollow column supported upon the bottom and over said central aperture and terminating at its upper end in a closed dome adjacent the removable cover, and a plurality of radially disposed equidistantly spaced conduits communicating between the interior of the column and the exterior of the body.

2. In a cream cooling means the combination of a cream cooling container comprising a cylindrical shell body terminating at its lower end in an annular supporting flange and at its upper end in an open filler throat, a removable cover for the upper end of the body, a bottom having a downwardly turned annular flange contacting throughout its length with and reinforcing the supporting flange of the body, said flanges being apertured to permit cooling fluid ingress, said bottom being centrally apertured, and a fluid circulating hollow column supported upon the bottom and over said central aperture and terminating at its upper end in a closed dome adjacent the removable cover, a plurality of radially disposed equidistantly spaced conduits communicating between the interior of the column and the exterior of the body, and a cooling liquid container having cooling liquid therein in which said first named container is supported upon its flanges with the radial conduits thereof im- Y mersed beneath the level of the cooling liquid for the purpose specified.

In testimony whereof I afliX my signature.
